Winfrey, who attended Tina Turner's wedding with German music producer Erwin Bach back in July, said that such a union is just not for her, News.com.au reported.
The talk show queen told Access Hollywood that she thought about hooking up with her beau at Turner's wedding, but then realised that things would not be really different after marriage.
Oprah admitted that if she and Stedman had got married, they probably wouldn't have lasted.
She said that she doesn't feel capable of handling responsibilities which come with the word 'wife'.
The 59-year-old added that although Stedman is a traditional man, they have a very untraditional relationship.
